May I ask you why don't you use WiFi?

@MaddogG sometimes, you are in a computer that doesnt have wifi.

Ok, but he doesn't have Bluetooth, too!

And I think still Bluetooth uses less energy even with these new powersave-modes in Wifi.

I nowadays have Bluetooth networking on always when at home and much of the maintaining and configuring I do over ssh from PC.
It does not take much battery having it connected via BT all the time, but I would guess (have not tried) doing same with WLAN would drain the battery.

I used to keep it connected through USB, but I am not happy N900's CPU running constantly at 500 Mhz when connected via USB. I hope there will be a hack in kernel-power for that some day.

This is a good reason, probably you are right...

You're right. But I think, calling ifconfig multiple times doesn't hurt though.


The reason I want to access my device via bluetooth is our restricted wifi at my work place. There, I can access the internet, but I cannot access my computer due to security policies. Sure, I can use the USB cable, but I often forget it at home.

It's nice to be able to access files on the phone via sftp without touching it by leaving it in the bag.

True, but if you also set up a default route, DNS-servers and Dummy-APN, like I have, it will hurt.

Would have to be something more specific so only started PAN connection would run the script.
If there would be pand program, one could just check with `pand -l` in the start of the script.
On PC side, I can see it is up:

Hi,
more than year later, I have the same question. I've started to play things as described elswhere on my debian squeeze, but soon I stucked on n900.

on root@n900:_________

/etc/bluetooth/main.conf and removed 'network,input,hal' from the
configuration option 'DisablePlugins'.

into /etc/network/interfaces I added

auto bnep0
iface bnup0 inet static
address 10.10.0.2
netmask 255.255.255.0
gateway 10.10.0.1

(even after reboot) I ran

ifup -f bnep0 (on ifup -v bnep0 it says 'interface already configured')
ifconfig bnep0 up 10.10.0.2
...ifconfig: SIOCGIFFLAGS: No such device

sabhack - did I forgot something?
thanks, j.

---edit----------------
ok, one thing is clear. Only after I try to connect over BT with nm-applet to "mymaemoname"_Network, the interfaces become available on both sides. No problem to add few lines to local /etc/network/interfaces (like
allow-hotplug bnep0
iface bnep0 inet static
address 10.10.0.3
netmask 255.255.255.0
# gateway 10.10.0.2
)

I must launch the ifconfig manually on n900.
However - I can have a bnep0 connection for about 30 seconds and after I get disconnected.... nm-applet just rotates ... these 30sec. This I dont know where it comes from, it doesnt happen for debian->BT->n900->mobile broadband.

Next thing: to be able to run dbus-scripts, I realized that it must be installed (from -devel?). I am not going to go that far, I am quite happy with the stability now. Are there any other solutions to respond automatically on n900 side?

-----next edit ------------- sorry ---------------------
after a lot of google ......
nm-applet 0.8, although it says it is ok, it has an issue with PAN
Finaly, I removed my bluetooth-applet, installed "blueman" and used blueman-applet. It didnt work neither, BUT, right-click/local services, I ticked group network, for "pan support" I tried to tick blueman (maybe a bug..., doesnt remember the setting) AND right-click/plugins I checked "DhcpClient" which unchecked "NMPANSupport". Than, "group network" from blueman started to work, nm-applet remained untouched and unaware.
My previous DUN setting in nm-applet remained ok (no idea where it is stored).
------------------
The only question remains, howto set
ifconfig bnep0 up 10.10.0.2
on n900 when PAN is started... without loading stuff from extra-devel.....
thanks, if there is any advice

Hi all

"allow-hotplug bnep0"
in /etc/network/interfaces seems to be ignored by maemo5 when connecting the n900 with bluetooth.
I only managed to bring up bnep0 by a dbus script:

NetworkManager with nm-applet seems to wait for a dhcp response. If there is no one, the connection times out and the bnep0 interfaces on both sides (n900 and debian squeeze) are removed. That's why we start dnsmasq to deliver exactly one address to the pc.

If you want to use the bnep0 connection from any n900 application for internet access (on the pc masquerading and forwarding must be enabled), you must use the "dummy network" for Internet connection (package libicd-network-null) and send a connection message for dummy on the system dbus.

BUT: why does not "allow-hotplug bnep0" work?
On the debian squeeze side it works flawlessly.

Hope this helps

I do have a reason:
I want to connect to my N900 from an android phone though bluetooth (via ssh) and want to be able to use aircrack or vnc
